actually i'll just contradict myself , seeing as a siren is a basic synth and not an fx processor it probably wont be in that book , but if you know a bit about soldering etc it shouldnt be too hard to make. its a typical VCO>VCA + LFO set up , and isnt too hard to make , but given that you could build a decent synth with not a lot more you're probably better off doing so , unless of course you want siren sounds only .

I was recently thinking about building a siren myself. I searched the net for instructions but didn't find anything you could use "as is". There are quite a lot of sites around with schematics for synthesizers. But I think these schematics are oversophisticated as they feature temperature compensation which is not necessary for a dub siren. (A siren doesn't have to be in tune..) I came across some basic schematics which may be useful as a starting point for experiments:

The next two schematics are taken from a electronics experimentation kit for kids ("Tonhohe" means pitch or frequency, "Lautstärke" means Volume, The "NF-Modul" is a amplifier module that can be used to connect the circuit directly to a speaker. You don't need this since you already have a sound system I guess ;-)

there is potentiometers for tone, frequency of oscillation and range of oscillation. you can modify it to change frequency of oscillation and tone. to do it, change c1 and (or) c2. you can add a switch selector to put different capacitors, so you will have different possibilities of frequencies.

I just received this circuit, and I'm going to build it as soon as I can. actually in august, most of electronic shops are closed, so I wait september. I don't have any idea if it sounds goods, but it seems...

HI all ! i've built the Siren, it works very well, especially whn you run it through a massive delay... i'm gonna set up the soundsystem next friday afternoon on the beach and have the box with me, jah bless. If anyone here lives in Israel (which i guess you don't) contact me via e-mail for more details.

Congratulations Toby! Did you use the schematic supplied by Munky Lee? It would be great if you could write a small documentation of your siren (maybe even with pics and realaudio-file). This would be a big help for other likeminded people!

Hi all, first of all big up 2 Daniel for setting up this joint , a pretty unique place indeed

then I'd like 2 know your opinions on this small idea I've had: a square wave with adjustable frequency (say 0-or-so-to-300 Hz) , to trigger on & off the sounds from your deck ( from only one aux possibly , not the main out ) , which is again fed into maybe an echo unit.. The problem is that I'm not that sure on actually how to build this thing... vco>transistor ?

I'll post again here (I'm planning 2 build the siren - thanks Mat for posting it ),in the meanwhile shoutz go out to all the true dubheads..

i was curious what a "dub siren" was, but it turns out i had already made one on the cheap out of a "magical musical stick", one of those dollar store keyboard sticks. take it apart, pull out the small circuit, snip the pitch resistor and solder in a 500k-ohm potentiometer in series with it, for siren sounds you can pitch down to a fat rumble. solder a switch between the 2 membrane contacts, and you've got a siren. maybe costs about $10, and would take about an hour to make and recase.

For the dub sirene from munky lee? It would be very nice, me have a little pit problems to read his schematic plan. It would it be nice if you can send me thi with a list of all Pieces that im need. Can some body do that please? Me overstand english an the german language.
